Ars reviews Aperture 1.1, and concludes: "I have to admit, I was very skeptical that Apple could whip together professional-quality RAW conversion for numerous camera models in a few months. Either they bought some existing technology we don't know about or there are some seriously overworked software engineers getting some much-needed sleep right about now. But who cares? The plain fact is that Aperture 1.1's high-quality RAW processing says "we can move quickly in areas where we've had little experience" and the discount/refund says "users won't be expected to beta test at their own expense again." Ars's review of Aperture 1.0 was quite negative.
